我成功地将图像直接上传到服务器文件夹，但我想将sme文本信息和图片一起存储到数据库中，并将图像存储在服务器中，路径存储在数据库中。。？
使用此代码。。。
字符串fileName=sourceFileUri；
HttpURLConnection conn = null;
DataOutputStream dos = null;
String lineEnd = "rn";
String twoHyphens = "--";
String boundary = "*****";
int bytesRead, bytesAvailable, bufferSize;
byte[] buffer;
int maxBufferSize = 1 * 1024 * 1024;
File sourceFile = new File(sourceFileUri);
if (!sourceFile.isFile()) {
dialog = ProgressDialog.show(CameraPhotoCapture.this, "", "Uploading file...", true);
dialog.dismiss();
Log.e("uploadFile", "Source File not exist :" );
runOnUiThread(new Runnable() {
public void run() {
// messageText.setText("Source File not exist :" +uploadFilePath + "" + uploadFileName);
}
});
return 0;
}
else
{

// open a URL connection to the Servlet

dos = new DataOutputStream(conn.getOutputStream());
dos.writeBytes(twoHyphens + boundary + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name=uploaded_file;filename="
+ fileName + "" + lineEnd);
dos.writeBytes(lineEnd);
// create a buffer of maximum size
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
buffer = new byte[bufferSize];
// read file and write it into form...
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
while (bytesRead > 0) {
dos.write(buffer, 0, bufferSize);
bytesAvailable = fileInputStream.available();
bufferSize = Math.min(bytesAvailable, maxBufferSize);
bytesRead = fileInputStream.read(buffer, 0, bufferSize);
}
// send multipart form data necesssary after file data...

我不能完全理解您的问题，但我认为您希望将有关文件的一些数据保存到数据库中。如果这确实是你的问题，请继续阅读。
将上传的文件从其原始文件名重命名始终是一种很好的做法。使用哈希创建一个新的文件名，并将文件（在本例中为图像）保存到webroot中的上传文件夹中。然后在数据库中插入一条记录，其中包含应用程序所需的所有信息。这样就不必像文件大小或mime类型那样查询文件系统。还要将原始文件名保存在记录中，包括一些关于图像的文本（我想这就是你想要做的）。我不会详细介绍代码，因为PHP有很多例子。
